I agree with Froggie! I have taken antidepressants for several years now, and am a walking testimony to the benefits....wish they had been available when I was a young person!
Like you, I have trouble talking to my mother about such things, but I did tell her, really not caring what her reaction would be, knowing that the medication is beneficial. She, and my father (now deceased) would have both benefitted from the same meds, but she will never do such, not understanding the workings of the meds.
If you are having anxiety about telling your mother about your medication, just wait until you feel comfortable mentioning it to her, or NOT! It's your life, your health, and you are doing the right thing for YOU!
Love,
Patty
